You may have a microphone issue. Try testing the individual microphones to see if they all work.

However, keep in mind that the iPhone 7 series of devices have proven to be very unreliable, suffering from flex-based issues similar to the iPhone 6 Plus (Touch Disease). On the iPhone 7, the fault line runs along the top of the SIM card reader and affects the Baseband CPU and Audio IC. Any short copper traces running perpendicular to the fault line while connecting to micro-BGA pads, is subject to failing.
On the Audio IC, this particularly affects the C12 pad/trace although there are 4 pads/traces along the fault line. Of those four, the C12 pad (I2S_AP_TO_CODEC_MCLK) is the most critical as it is a communication protocol line between the CPU and the Audio IC.
Here are the typical symptoms, as collated by the repair community:
This is a repairable problem but it requires a micro-soldering repair. Although it can be a routine repair for an experienced tech, it can go sideways very quickly as the Audio IC is directly opposite the underfilled Baseband CPU. An unqualified tech can apply too much heat and cause massive problems. So do your due diligence.
Opa! Mudei de ideia.
